Another jazzy idea
ocurred to me.
My biggest trouble is to get rid of the maleic acid, which obviously interfears with the hydrolysis, rendering it worthless.
So, instead using tonnes of solvent and years of time, to extact a couple of milligrams of ergometrine freebase, maybe there is a simple and easy way, to substitute the Maleic acid with Tartaric acid.
Tartaric acid seems not to interfear with the hydrolysis, at least it did not with the Ergometrine Tartrate, I used in the past.
It was so beautifull. After the hydrolysis I would let cool down to about 10 C in the fridge, then neutralise with just some dilute H2SO4, and right away, black crystalls would appear, during the addition, with the first drop. After cleaning (Washing with dilute H2SO4)and grinding, they would be somewhat offwhite. And they would give fine endproduct too.
Ok, soxhlet is a possibilty, but it inhibits the necessity to obtain at least a couple of extracting columns, which are quite expansive.
On the other hand, I know that in Europe, some people are working with this material successfully and very fast.
(no komplaints whatsoever, better results than with et.)
They are adjusted to et, but had no trouble at all, to adjust themself to ergometrine tartrate, in fact, they seem to have the ideal way how to do it. This I have to find out. (and they wont tell me, of course)
I'll keep on looking, thank you all for you effort.
